One curious thing about 8.8.8.8 (and 8.8.4.4) is that it gets redirected to the closest Google CDN.

DNS is something that’s commonly Anycasted. In laymen’s terms, basically what that means is rather than 8.8.8.8 pointing to one server (or a load balanced cluster in one DC) as you might expect, it rather points to potentially thousands of servers all over the globe and the closest one (BGP route wise) is the one picked for you.

8.8.8.8 is already an IP address so DNS is not involved. The anycast is handled by just BGP.

I think the parent meant that anycast is often used for DNS servers, not that a DNS lookup is used to find the closest Google DNS server.
